Title: Improvements in or connected with variable speed gearing for motor road and other vehicles
IPC: F16H63/38
Filed: 1921-03-23
Abstract: 183,524. Wade, E. J., and Jacobs, G. W. March 23, 1921. Controlling variable-speed gearing.-In motor vehicles, provided with an auxiliary change-speed gear between the ordinary gear-box and the road wheels, the neutral or disconnected positions of the auxiliary gear are rendered unstable, so that the propeller shaft, and any brake mechanism thereon, are never left accidentally disconnected from the road wheels. The auxiliary gear is carried in a casing b and is controlled by a handlever f and a selector rod a. The selector-rod is retained in the various gear positions by means of a spring-pressed pin d engaging notches c in the rod, these notches meet at the top of the rod so that there is no stable position for the rod except in the gear positions. The hand-lever may be retained, when desired, in an out-of-gear position by means of a pivoted fork or latch g. The spring-pressed pin may act upon the hand-lever instead of on the selector-rod. Specification 142,032 is referred to.

Title: Process for the manufacture of iron from iron-ores
IPC: C21B13/14
Filed: 1920-03-30
Abstract: 163,561. Vermaes, S. J., and Syndicaat Electro-Staal. March 30, 1920. No Patent granted (Sealing fee not paid). Extracting.-Iron in finely grained condition is heated directly up to 1100‹ C. or higher, for example in a rotary kiln, and then transferred to a reduction furnace indirectly heated. Fluxes may be added before preheating or may be separately heated and mixed in the reduction furnace, to which is also added carbon or coal as required for complete reduction of the ore. The temperature is maintained above 1000‹ C. but below the melting-point of iron. The solid, sintered mass of iron formed is discharged, without admission of air, into another furnace where it is melted and slag removed; the iron may be further purified and carbonized in another smelting-furnace. A part of the gases liberated in the reduction furnace and consisting of carbon monoxide (and hydrogen and hydrocarbons if the fuel is coal) is burnt in the heating-channels of the reduction furnace, a second part is used for heating the smelting-furnace, and a third part may be used for pre-heating the ore and fluxes by direct contact with the combustion products.

Title: Improvements in or relating to the manufacture of flour
IPC: A21D6/00
Filed: 1927-06-10
Abstract: 300,537. Fisher, E. A., and Jones, C. R. June 10, 1927. Divided on 300,291. Treating with air; treatment by damping.- Flour is passed at a known rate from a conveyer a down a shoot b on to a rotating disc c by which it is broken up and thrown centrifugally into a thin cloud. A stream of heated and humidified air entering at the lower end e of the chamber is driven upwards past the disc c at such a velocity as to carry the flour through a duct f into an expansion chamber g similar to a cyclone dust collector. The temperature of the flour is thus raised to and maintained approximately within the limits of 130' and 180' F. without substantial loss of moisture. The flour is deposited in the chamber g and is carried by a conveyer k to a heat insulated box or bin where it lies, if necessary, till the treatment is complete. The air passes out through textile fabric and over a series of baffle plates j and may then be recirculated. The humidity -of the leaving air should be preferably over 90 per cent relative humidity. As an example, after treating a low grade flour the temperature of the air leaving the expansion chamber was 140‹ F. and its relative humidity 90 per cent; the flour was passed once through the plant and subjected to ten minutes lying in the bin. The temperature reached by the flour was 140‹ F. and its moisture content was substantially unaltered. After leaving the bin the flour may be cooled in a second machine by blowing humidified air through it, or it may be led into a second chamber where it may be cooled and moistened by spraying with cold air and finely atomized water, or it may be cooled in any other manner. The treatment may be applied to finished flour, to intermediate products such as semolina, middlings, and dunst, or to any or all of the various "divides." Specification 300,291 is referred to.
